Restrictions on the use of synthetic antioxidants are being imposed because of their toxic properties. The present study is the continuation of a program aimed at investigation on antioxidant activity of extracts from medicinal plants and to identify alternative natural and safe sources of food antioxidant especially from plant origin. In this report the anti-peroxidative effect of alcoholic ex...
دو گونه Rosa canina و Rosa beggeriana به علت دارا بودن خصوصیات مطلوب از جمله رشد سریع و معطر بودن اهمیت قابل توجهی دارند. با توجه به مشکلات تکثیر رز از طریق روش‌های سنتی، استفاده از روش های ریزازدیادی توصیه شده است. از جمله مشکلات کشت این ویترو نیز می توان به پدیده زردشدگی برگ ها اشاره نمود. لذا در این پژوهش جهت افزایش سبزینگی برگ‌ها، دو آزمایش طراحی شد. در آزمایش اول محیط کشت MS تغییر یافته (آ...
Two borate esters, one with benzotriazole (BTB) and another 2-mercaptobenzothiazole (BMB) were synthesized used as additives in mineral oil. BMB showed better hydrolysis stability, probably because S atoms provided negative charges to the N enhance B←N coordination. Moreover, was superior terms of improving PB value, anti-wear friction-reducing properties XPS spectra revealed that h-BN, B2O3 Fe...
This study was conducted in the division of food science and technology SKUAST-Jammu which physicochemical analysis fruit persimmon (Diospyros kaki L) done year 2020. The colour values L*, a*,b* values, crude protein content, fat solubility per cent, fibre, TSS, ash total sugars ascorbic acid mg/100gm, phenolic compounds mg GAE/g, Carbohydrates cent ,FRAP nmol FeSo4/g were assessed. (L*) value ...
Aqueous extract of T. cordifolia inhibited Fenton (FeSO4) reaction and radiation mediated 2-deoxyribose degradation in a dose dependent fashion with an IC50 value of 700 microg/ml for both Fenton and radiation mediated 2-DR degradation. Similarly, it showed a moderate but dose dependent inhibition of chemically generated superoxide anion at 500 microg/ml concentration and above with an IC50 val...
The main objective of the study is to enhance the mevastatin production using Plackett-Burman (PB) and central composite design (CCD) by Aspergillus terreus in submerged fermentation (SmF). Eight nutrients were chosen for a PB design with 12 experimental runs. A maximum mevastatin production of 170.4 mg L-1 was obtained in PB design. Response surface methodology (RSM) is a sequential procedure ...
Antioxidant, anti-glycation and anti-inflammatory activities of fresh and conserved peach fruits (Prunus persica L. Batsch) were compared. Fresh peach pulps, peels, preserve peach pulps and the preserve syrup were prepared at equal concentrations. Rat liver, kidney and brain cortex tissue slices were pre-incubated with peach samples, subjected to oxidative stress with FeSO4 and hydrogen peroxid...
